Abstract
A refrigerated display case having an improved air outlet nozzle is disclosed. The display case includes an insulated enclosure having an access opening in the front and means for establishing an air curtain across the opening from an upper air outlet to a lower air inlet. A nozzle structure is removably disposed on the discharge opening to define the air stream layer. The nozzle is formed as a gridlike honeycomb section having a plurality of flat tube elements each of which are stacked against each other and bound together through a removable fastening device. This facilitates maintenance of the nozzle. The flat tube elements may also be formed having air passageways of progressively differing cross sectional areas to decrease turbulance between the air stream and adjacent ambient air.
